LF2570VA Precision Molded Aspheric Lens

Fiber Type SM; Wavelength Detection 800-1700 nm; Test Tones 0.27, 1, 2 kHz; IL 0.8, 2.5 dB; Power Detection Range -50-+10 dBm Kingfisher’s KI 6171 tone and traffic identifier is a rugged, easy to use instrument used to identify optical test tones, live traffic and optical power levels in single mode (SM) fiber. KI 6171 optical fiber identifiers are commonly used during installation and maintenance of fiber optic systems to positively identify fibers to avoid accidently disconnecting live systems, and for general checking of continuity, faults or mid-span loss points. The KI 6171 optical fiber identifier is easy and reliable to use with one hand. It can detect a variety of optical tones, which can be provided by any Kingfisher laser source. When traffic is present, an audible tone can be heard as well as LED indication of traffic direction and estimated core power. Various field interchangeable chucks are supplied and enable rapid re-configuration for a variety of fiber cord diameters. Chucks not in used are securely stored and conveniently carried along with the equipment in the slide-on compartment hence reducing chances of those chucks being misplaced. The approximate core power in the fiber is measured and displayed on a two-digit display. Its very long distance operating range of up to 200 km makes the KI 6171 optical fiber identifier suitable for use where a VFL cannot reach.
